Chondrodermatitis nodularis helicis - Skin in Adult

Alerts and Notices

Synopsis


Chondrodermatitis nodularis helicis (chondrodermatitis nodularis chronica helicis et antihelicis) is a benign, common inflammatory condition of the helical or antihelical cartilage and overlying skin with an exquisitely tender, small erythematous nodule or nodules. Patients preferentially sleep on the side of affected ear and cannot avoid doing so. Phone usage on the affected side is common. Repeated trauma, pressure, and subsequent ischemic necrosis of the affected cartilage and overlying dermis are felt to promote this condition. Cold, radiation therapy, and actinic damage may be exacerbating factors. It is more common in middle-aged to elderly, fair-skinned men. In men, the lesion favors the helix, whereas in women, the antihelix is more commonly affected. There have been no reports of malignant degeneration.
